Our giant tunnel boring machines are making steady progress underground, digging 24 hours a day to build the future Metro Tunnel. And they’re not the only ones working around the clock. Come take a rare look from inside the cabin and meet one of the operators behind the (figurative) wheel. 🧐 This is the first of our Digging Deeper series, where we give you are more in depth look at how we are building the Metro Tunnel. Let us know what you think in the comments! | Metro Tunnel
